Description

Technical Field

[0001] This invention relates to the field of ultrasonic welding technology, specifically to an ultrasonic welding apparatus with a protective structure. Background Technology

[0002] Ultrasonic welding utilizes high-frequency vibration waves transmitted to the surfaces of two objects to be welded. An ultrasonic generator converts a 50 / 60 Hz current into 15, 20, 30, or 40 kHz electrical energy. This converted high-frequency electrical energy is then converted into mechanical motion by a transducer. This mechanical motion is transmitted to the welding head via an amplitude transformer. Finally, the welding head transfers the received vibration energy to the joint of the workpieces to be welded. Under pressure, the surfaces of the two objects rub against each other, forming a fusion between molecular layers.

[0003] Currently, desktop ultrasonic welding equipment requires manual stacking of two workpieces to be welded during actual use, and then the stacked workpieces are placed on the welding carrier. However, this process has certain drawbacks. Since the two workpieces are stacked manually, the determination of the reference surface of the two workpieces depends entirely on the skill of the operator. If there is an error in the reference surface of the two workpieces, it will result in defective products. At the same time, as the working hours increase, the efficiency of frequent manual loading and unloading of products will also decrease accordingly, which will affect the welding efficiency.

[0004] In view of this, an ultrasonic welding device with a protective structure was designed to solve the above problems. Summary of the Invention

[0011] In a preferred embodiment, the present invention may be further configured such that: the automatic welding assistance mechanism further includes two pads, and the two pads are fixedly installed at the other end of the rectangular slot, and the top surface of the top beam plate is flush with the top surface of the two pads;

[0012] The bottom of the welding station is equipped with four fourth bolts. The chassis is fixedly installed on the welding station by the four fourth bolts. The motor is fixedly installed inside the chassis. The drive pulley is installed on the motor. The linkage pulley is installed on one of the shafts.

[0013] In a preferred embodiment, the present invention can be further configured such that: two second bolts are inserted inside the stabilizing pad, and the threaded sections of the two second bolts are installed inside the welding station; the positioning rod is inserted into the other end of the top beam plate, and both ends of the positioning rod are engaged inside the welding station.

[0014] The discharge pad is mounted on the top beam plate by two third bolts.

[0015] In a preferred embodiment, the present invention can be further configured such that: the middle part of the top beam plate and the middle part of the bottom beam plate are both provided with circular end faces, and the circular end face of the middle part of the top beam plate is used to support the workpiece to be welded, while the circular end face of the middle part of the bottom beam plate is used to enhance the shaking amplitude of the lateral movement of the multiple sets of clamping mechanisms after bottoming.

[0016] In a preferred embodiment, the present invention can be further configured such that the conveyor belt has a T-shaped cross-section and the side of the conveyor belt is provided with protrusions to enhance the lateral protection of the carrier plate and control the maximum opening angle of two adjacent clamping plates.

[0018] In a preferred embodiment, the present invention can be further configured as follows: the inner end of the load-bearing plate is provided with a slot, a plurality of pre-tightening rods are installed in the slots of the two load-bearing plates, a clamping plate is installed on the outside of the pre-tightening rods, and the clamping plate is located at the center of the inner side of the two load-bearing plates, and the outer end of the clamping plate is provided with a groove adapted to the circular end face.

[0021] By adopting the above technical solution, the beneficial effects achieved by the present invention are as follows:

[0022] 1. This invention uses the center position of the inner side of two calibration plates as the initial point of two conveyor belts. As the two conveyor belts carry multiple sets of clamping mechanisms that are evenly distributed, the two adjacent clamping plates, after passing the flared pad, passively expand to the maximum angle and can centrally clamp the two workpieces pre-stacked in the feeding frame. After the two conveyor belts have rotated one cycle, the two clamped workpieces will eventually be located in the middle of the inner side of the two calibration plates, which is convenient for subsequent welding of the workpieces.

[0023] 2. This invention installs an upward-facing discharge pad at the end of the top beam plate, with the inclined surface of the discharge pad facing the direction of workpiece travel. When the welded workpiece passes through the discharge pad and is pressed upward along its inclined surface, the welded product can be quickly peeled off. After the two adjacent clamping plates lose their clamping of the workpiece, they are automatically reset by springs, thus preparing for the transfer of subsequent workpieces. This enables automated loading and unloading of the desktop welding platform, improving workpiece production efficiency.

[0024] 3. This invention involves opening a feeding trough on the welding platform and connecting the feeding trough to the unloading frame. A horizontally placed baffle is movably installed directly above the unloading frame. When two workpieces are sequentially transferred into the unloading frame by an external conveying mechanism, the two types of workpieces, which are spaced apart, are stacked vertically under the lateral limiting action of the baffle. They are then clamped by a clamping plate. During the upward transfer of the two clamped workpieces, the baffle will flip upward around the horizontal axis, thereby realizing the transfer of the workpieces. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0042] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0043] The following describes, with reference to the accompanying drawings, some embodiments of an ultrasonic welding apparatus with a protective structure.

[0044] Example 1:

[0045] Combination Figures 1 to 10As shown, the present invention provides an ultrasonic welding device with a protective structure, including a control body 100 and an automatic welding assistance mechanism 200 mounted on the control body 100. The automatic welding assistance mechanism 200 is mounted on the control body 100, two conveyor belts 400 are movably mounted within the automatic welding assistance mechanism 200, and multiple sets of clamping mechanisms 500 are evenly distributed on the two conveyor belts 400. The automatic welding assistance mechanism 200 is used to automatically control the loading and unloading of two types of workpieces after stacking, and to provide support for the two conveyor belts 400. The two conveyor belts 400 are used to provide effective support for the conventionally evenly distributed multiple sets of clamping mechanisms 500. The clamping mechanisms 500 are used to clamp the two types of workpieces after pre-stacking, and cooperate with the ultrasonic welding machine 300 to perform welding operations.

[0046] The automatic soldering mechanism 200 includes a soldering station 210, and four bearings 2105 are installed inside the soldering station 210. A shaft 2104 is installed inside the soldering station 210 through two bearings 2105, and the number of shafts 2104 is two.

[0047] The welding station 210 has a rectangular slot in the middle, and a stabilizing pad 250 is installed at one end of the rectangular slot. The bottom beam plate 2501 and the top beam plate 2504 are both fixed to the stabilizing pad 250 by studs and nuts. The bottom beam plate 2501 is located directly below the top beam plate 2504. The flared pad 2502 is fixedly installed at the bottom of the bottom beam plate 2501, and the discharge pad 2505 is fixedly installed at the top of the top beam plate 2504.

[0048] Two symmetrically distributed calibration plates 220 are fixedly installed at the center of the top surface of the soldering station 210, and a scale is provided on the top of the calibration plate 220, with the middle of the top surface of the calibration plate 220 as the initial point for counting.

[0049] The soldering station 210 has a feeding groove 2101 and two sliding grooves 2102 inside. Two first bolts 2103 are fixedly installed at the bottom of the soldering station 210. The feeding frame 230 is fixed to the soldering station 210 by the two first bolts 2103, and the feeding groove 2101 is connected to the feeding frame 230. The sliding rod 2402 is movably installed in the two sliding grooves 2102. The top of the traction plate 2403 is movably installed on the sliding rod 2402. The bottom end of the traction plate 2403 is movably installed with an end shaft 2404. The baffle 2401 is movably connected to the traction plate 2403 through the end shaft 2404, and a horizontal shaft 240 is inserted into one end of the baffle 2401 near the inner wall of the rectangular slot.

[0050] The horizontal axis 240 is mounted on the inner wall of the rectangular slot;

[0051] Four fourth bolts 260 are installed at the bottom of the soldering station 210. The chassis 2601 is fixedly installed on the soldering station 210 by the four fourth bolts 260. The motor 2602 is fixedly installed inside the chassis 2601. The drive pulley 2603 is installed on the motor 2602. The linkage pulley 2605 is installed on one of the shafts 2104. The transmission belt 2604 is connected to the drive pulley 2603 and the linkage pulley 2605.

[0052] Two conveyor belts 400 are connected to the outside of two shafts 2104, and the two conveyor belts 400 are located inside the rectangular slot. The cross-section of the conveyor belts 400 is T-shaped, and the sides of the conveyor belts 400 are provided with protrusions to enhance the lateral protection of the carrier plate 540 and control the maximum opening angle of the two adjacent clamping plates 5501.

[0053] The clamping mechanism 500 includes two load-bearing plates 510 fixedly installed on two conveyor belts 400, and a slide rail 5101 is provided inside the load-bearing plate 5101. A clamp 5401 is movably installed in the slide rail 5101. A carrier plate 540 is fixedly installed outside the clamp 5401. A buckle plate 560 is snapped into the carrier plate 540. A back clamping block 550 and a clamping plate 5501 are snapped into the buckle plate 560. The clamping plate 5501 and the carrier plate 540 are in a vertical structure.

[0054] Multiple anti-slip rubber strips are fixedly installed on the inner side of the clamp 5501 in a longitudinal direction.

[0055] Two types of workpieces, spaced apart, are pre-transferred into the feeding trough 2101 using an external conveying mechanism. After the first type of workpiece enters from the feeding trough 2101 and is temporarily stored at the bottom of the inner side of the discharge frame 230, the second type of workpieces delivered subsequently will continue to be transferred along the feeding trough 2101 into the discharge frame 230. At this time, the second type of workpieces will be arranged sequentially along the top of the first type of workpieces.

[0056] When the motor 2602 is started, its internal transmission shaft, in conjunction with the drive pulley 2603, will drive the transmission belt 2604 and the linkage pulley 2605. The linkage pulley 2605 will drive one of the shafts 2104 to rotate, and the two shafts 2104 will drive the two conveyor belts 400 to rotate at a constant speed along the inner side of the rectangular slot. At this time, the multiple clamping mechanisms 500 installed on the two conveyor belts 400 can rotate at a constant speed along the inner side of the rectangular slot.

[0057] Until the two adjacent clamping plates 5501 pass the flared pad 2502, the two clamping plates 5501, which are laterally squeezed and expanded to the maximum angle by the flared pad 2502, will move to the top of the feeding frame 230. The two types of exposed and stacked workpieces can be quickly clamped. Finally, the two types of workpieces clamped and stacked by the two clamping plates 5501 will push the baffle 2401 to flip upward and transfer upward until the two types of stacked workpieces move to the center position inside the two calibration plates 220 and stop. After the ultrasonic welding machine 300 runs and descends to press against the upper surface of the top workpiece, the workpiece carried by the top beam plate 2504 can be quickly assisted in welding.

[0058] The workpiece after welding is transferred towards the discharge pad 2505 and eventually completely detaches from its outer surface.

[0059] Example 2:

[0060] Combination Figures 3 to 8 As shown, based on Embodiment 1, the automatic welding assistance mechanism 200 further includes two pads 2106, and the two pads 2106 are fixedly installed at the other end of the rectangular slot, and the top surface of the top beam plate 2504 is flush with the top surface of the two pads 2106.

[0061] The stabilizing pad 250 has two second bolts 2503 inserted inside, and the threaded sections of the two second bolts 2503 are installed inside the welding station 210. The positioning rod 2506 is inserted into the other end of the top beam plate 2504, and the two ends of the positioning rod 2506 are snapped into the inside of the welding station 210. The discharge pad 2505 is installed on the top beam plate 2504 by two third bolts 2507.

[0062] Both the top beam plate 2504 and the bottom beam plate 2501 have circular end faces in the middle. The circular end face in the middle of the top beam plate 2504 is used to support the workpiece to be welded, while the circular end face in the middle of the bottom beam plate 2501 is used to enhance the amplitude of the lateral movement of the multiple clamping mechanisms 500 after the bottom is placed.

[0063] Preferably, the width of the flared pad 2502 is twice the width of the discharge pad 2505, and the end of the flared pad 2502 facing the direction of travel of the clamping mechanism 500 has an arc-shaped structure, and both the bottom beam plate 2501 and the top beam plate 2504 are made of stainless steel.

[0064] Specifically, the bottom beam plate 2501 and top beam plate 2504, which are symmetrically distributed along the rectangular slots, can enhance the stability protection during the rotation of the multiple clamping mechanisms 500. When the ultrasonic welding machine 300 runs and descends and presses against the upper surface of a workpiece, the other end of the top beam plate 2504 is supported by the positioning rod 2506. Therefore, the circular end face in the middle of the top beam plate 2504 can remain stable during the pressure period, avoiding the workpiece from being continuously pressured and misaligned due to the vibration of the top beam plate 2504 during welding.

[0065] Example 3:

[0066] Combination Figure 6 and Figure 10 As shown, in the above embodiment, an outer plate 5102 is fixedly installed on the outer end of the load-bearing plate 510, and a transverse groove adapted to be snapped onto the side of the conveyor belt 400 is opened at the bottom of the outer side of the outer plate 5102. A through hole is opened in the middle of the outer plate 5102, one end of the guide rod 570 is inserted into the through hole, and the other end of the guide rod 570 passes through the interior of the slide rail 5101. A spring 5701 is provided on the outside of the guide rod 570, and the two ends of the spring 5701 are respectively pressed on the outer plate 5102 and the clamp 5401.

[0067] The inner end of the load-bearing plate 510 is provided with a slot, and multiple pre-tightening rods 530 are installed in the slots of the two load-bearing plates 510. A template 520 is installed on the outside of the pre-tightening rod 530, and the template 520 is located at the center of the inner side of the two load-bearing plates 510. The outer end of the template 520 is provided with a groove that fits the circular end face.

[0068] The preload rod 530 consists of two anti-slip rubber prongs and a metal rod, with the anti-slip rubber prongs fitting and pressing against the inner wall of the slot.

[0069] Preferably, the load-bearing plate 510 is bonded to the outer surface of the conveyor belt 400, and both end faces of the carrier plate 540 that contact the load-bearing plate 510 are polished and coated to reduce the frictional resistance of the carrier plate 540 sliding laterally, while the clamping plate 5501 and the back clamping block 550 are welded.

[0070] Among them, the two ends of the metal rod inside the pretension rod 530 are provided with threaded sections, and the anti-slip rubber column head is installed on the metal threaded section by a nut, which is used to adjust the distance between the two load-bearing plates 510.

[0071] When the two clamping plates 5501 are pressed by the spring to clamp the two stacked workpieces, the anti-slip rubber strips on the inner side of the clamping plates 5501 can enhance the stability between the two stacked workpieces and avoid the risk of misalignment after the workpieces are transferred and touch the baffle 2401.

[0072] The working principle and usage process of this invention: The control unit 100 is set on the ground in the working area in advance. When in use, the motor 2602 is started through the client. As the motor 2602 and the drive pulley 2603 drive the transmission belt 2604 to rotate, the other end of the transmission belt 2604 will assist the rotation of the linkage pulley 2605 and one of the shafts 2104. At this time, the driven shaft 2104 and the other shaft 2104 can drive the two conveyor belts 400 to rotate at a constant speed.

[0073] At the same time, the products to be welded are delivered into the feeding trough 2101 by an external conveying mechanism. After the products are delivered from the feeding trough 2101, they are guided by the feeding frame 230 and can be temporarily stored in sequence.

[0074] When the two conveyor belts 400 rotate and drive the evenly distributed multiple sets of clamping mechanisms 500 to rotate regularly along the inside of the welding station 210, when two adjacent clamping plates 5501 move to the underside of the welding station 210 and pass the flaring pad 2502, the two clamping plates 5501, guided by the front end of the flaring pad 2502, will gradually expand until they reach their maximum expansion and detach from the flaring pad 2502. At the instant, the outermost product located inside the feeding frame 230 can be quickly clamped by the two clamping plates 5501 at their maximum angle and, driven by the two conveyor belts 400, is clamped... The product can then be moved directly above the welding station 210 until it reaches the center of the inner side of the two calibration plates 220. The bottom of the product will then be located on the circular end face of the top beam plate 2504. As the ultrasonic welding machine 300 descends and fits against the top of the product, the circular end face of the top beam plate 2504 can provide effective support and protection for the product during welding. At the same time, the two calibration plates 220 can limit the descent height of the ultrasonic welding machine 300 while calibrating the welding points of the product, thus preventing the ultrasonic welding machine 300 from descending too far and causing over-welding of the product.

[0075] After welding is completed, the two rotating conveyor belts 400 will carry the welded product toward the discharge pad 2505 until the bottom of the product in the direction of travel is squeezed by the inclined surface of the discharge pad 2505 and detached. At this time, the welding device can realize the integrated process of automatic feeding and automatic welding of the product, thereby improving the efficiency of product welding, saving labor costs, and further improving work efficiency.

[0076] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
